This invention relates to new and useful lmprovements 1n spear poles forremovlng paper from the rollers of paper making mathey will chines whenthe same become clogged.

WVhen therollers of paper making machines become clogged, it isnecessary tore move the paper by poles carrying knives. If hard woodpoles are used for this purpose, frequently tear from the rollers thefelt covering which is very expensive to replace.

On the other hand, solid soft wood poles, which will not tear the felt,are not strong enough to remove the paper from the rollers when theybecome clogged up.

To provide a,wood pole which will have suflicient strength to removepaper from the clogged paper-making machine rollers withthe structure isout tearing felt from them is the object of this. invention. Such a poleI construct of lami nated softwood such as 'white pine. B making itthree ply, the strength of the pole is doubled and still it is softenough not to injure the "felt on the rollers. a I

In the accompanying drawings illustrating my invention, view of mylaminated spear pole. Figure 2 is a cross sectional view taken throughthe same before it is turned. And Figure 3 is a cross sectional viewtaken through the same after it has been turned. to cylindrical form.

Referring to the for a detailed description of my invention,

the numeral 1 designates a soft wood spear my hand this 20th Figure 1 isa perspective a lathe. The pole shown in Figures 1 and 3 is the result.It is strong enough to remove 7 paper from the clogged paper makingmachlne rollers without breaking, and will not injure the felt on themduring the removal operation. 1 Having described my invention,-Iclaim: 1. i A laminated soft woodspearpole for re moving paper from theclogged up rollers of a paper making machine. A spear pole for removingpaper from the clogged up rollers of a paper making machine, comprisinga plurality of soft wood strips glued together and turned to cylindricalform. V

3. spear pole for removing paper from the clogged up rollers of a papermaking machine, comprising three soft wood strips glued together andturned to cylindrical form, and atongue and groove connection 7 betweenthe middle strip and the outer ones.

In testimony whereof I have hereunto set day of November, 1929.
